What Is Number Base Converter?
Convert numbers between binary, octal, decimal, and hexadecimal bases.
Computers represent numbers in different bases: Binary (base 2) uses only 0 and 1, and is the native language of digital hardware. Octal (base 8) was historically used in computing and is still seen in Unix file permissions. Decimal (base 10) is the human-standard number system. Hexadecimal (base 16, 0–9 + A–F) is widely used in programming for memory addresses, color codes (#FF5733), and bytecodes.
